" Application filed August 22, 1894. Serial No. 521,044. (No model.) l

To @ZZ whom t may concern.:

Be it known that I, HENRY GEISENHNER, a citizen of the United States, residing at Schenectady, in the county of Schenectady' and State of New York, have invented certain new and useful Improvements in Apparatus for Winding Armature-Coils, of which the following is a specification.

My invention relates to the manufacture of armature coils forv dynamo-electric machines; and has for its object to provide an apparatus by which such coils may be made rapidly and accurately, at the same time being capable of "ready insulation and being made in completed, they become practically integral interchangeable form; while, when partially in construction although formedv of a number of convolutions, thus affordinggreat facility in the subsequent handling necessary, in their efficient insulation, and in their application'to the armature core. I do not however in this lapplication claim either the coil itself or the method of forming the same, as these are not my invention, my claims being restricted to the apparatus which I have devised for their ready manufacture; although I donot mean to limit myself to the apparatus shown and described, as it may be varied in form without departing from the principles involved.

My invention then consists in a tool or apparatus by which the coil may be formed first of a number of convolutions .lying side by Yside in the same vertical'plane, the two parts of the coil being approximately straight, and then ybeing pulled open sidewise so as to form the coil into a six-sided figure, the pulling open sidewise at the same time bringing the ends of the coil nearer together and the whole operation keeping the Wires composing the coil under .tension so that the parts between the points of iexure are straightened; or, v more accurately, shaped to the true curve resOA quired in some parts, and straightened in others. t

The accompanying drawings show my improved apparatus, and therein- Figure l is a perspective viewlooking to the right with the coil in its first position; Fig. 2, a perspective view looking to the left With the coil in its second position and substantially completed. Fig. 3 is a cross-'section upon the line 3 3 ot' Fig. l and upon a smaller scale a'nd with the channel-irons in position at the sides of the apparatus; and Fig. 4 is a perspective view of the appliance which I use to effectually straighten the sides of the coils and put the wires under an equal tension.

Referring by'letter, A is the body of the tool, formed of thin metal, preferably by casting. In practice I have used a brass composition, although this part of the tool may be made of any appropriate substance having the requisite strength. As illustrated in Fig; 3, it presents a curved or approximately cylindrical surface which is preferably of the same radius as the armature core upon which the coils are to be applied, although minor variations from this are immaterial. Upon each side of the body piece A I secure achannel-iron B. The wires of the coils are designed to pass through the groove or channel in this part'of the apparatus and to be secured firmly therein by the buttons D, D. The top and bottom of the groove are rounded off in the direction of erxure of the lcoil so that the Wires may not be bent against a sharp edge. Attached to this channel-iron andon the opposite side of the body-piece is a block or plate C, and through the block and the projecting part ot' the channel-piece B is a hole C for the insertion of the stretching tool illustrated in Fig. 4. This plate or block C is'designed to secure the channel-piece B in place so that it may reciprocate upon one surface of the body A, the block C and the projecting part of the channel-piece having a bearing in the slot A2 cut in the body A. One of these channel-pieces B is upon each side of the apparatus, and whenA the coilv is being Wound they register with each other in the same ver-k tical plane.

Upon the body piece A is a bossG by which it is secured to asuitable upright support, not shown. The edge A of the piece A is cast thicker, and, as shown in Fig. 3, has a small groove a upon the part opposite the slot A2, the groove being designed to take the end of the screw in the tool shown in Fig. 4. Acen- IOO tral portion a of the body piece A in the line of the slots A2 is left to strengthen the structure, and to form a stop at the center for the channel-pieces B, B.

At the top and bottom of the body piece are reciprocating slides E held in place by pins F in holes f,f, registering with similar holes f' in the thickened upper and lower portions of the body piece A. Upon the ends of these slidesl are projecting blocks E', E also held in place by suitable pins e, e.

The operation of Winding a coil upon my improved apparatus is as follows: The coil is first wound with the tool in the position shown in Fig. 1, preferably with an operator upon each side of the tool, and after the wire is in place and the ends secured together, the buttons D, D are turned to prevent the wire jumping out of the groove in the channelpiece B. The clips h, 7L are slipped under itto hold the wires in place, the pins F, Flare withdrawn, and the channel-pieces B, B are then moved from the center to the sides of the apparatus, shaping the coil as shown in Fig. 2, and at the same time pulling down the slides E, E to the position shown in that Iigure. The tool shown in Fig. 4 is placed in position, as illustrated in Fig. 2, with its end C2 engaging with the hole C', and the screw I2 engaging with the groove a inthe part A of the body piece A. This screw has a corresponding thread in the pintle I' which revolves in the body part I of the tool. The screw I2 is then turned (it being understood that two of the tools I are employed, one upon each end), until the coil is stretched tight. The blocks E', E are then moved, either by 'slipping out the pins e or by turning the blocks about the pins as an axis, and the coil is removed from the form, after which it is wrapped with insulating tape, and the clips h removed. More insulation is then applied in the usual Ways, if necessary, this forming no part of my invention.

The blocks E', E may be bodily removed to remove the coil more easily, and other means of stretching the coil might be employed without affecting the principle of my invention; and it is manifest that variations of form in the tool may be made. Mere modifications such as these I aim to embrace in the claims annexed to this specification.

What I claim as new, and desire to secure by Letters Patent of the United States, is-
